Tiny AVR Programmer Hookup Guide
Before you can start using the Tiny AVR Programmer, you may need to set it up on your computer. If you’re using a Mac or Linux machine, you don’t need to install drivers. Just plug the board in, and skip to the Programming in Arduino page.
If you’re using any version of Windows, you’ve got a few steps to follow before you can join your Mac/Linux comrades.
Step 1: Plug the Programmer In
To begin, locate an empty USB port on your computer, and plug the Tiny AVR Programmer into it. You’ll probably want to have the programmer close by. If you’re using a PC, or your USB ports aren’t close by, a USB Extension Cable might help get the programmer into a more convenient spot on your desk.
Step 2: Wait for Windows to Automatically Fail/Succeed
After plugging in your Tiny AVR Programmer, Windows will try to look for a driver that matches it. Keep an eye on the notification area in the bottom-right corner. Wait for Windows to try to install the driver on its own. There’s a chance that, after searching, Windows will find the driver. If you get a Device driver software installed successfully notification (lucky you!), you can ignore the next few steps. But, if you got something like this:
Continue on to step 3…
Step 3: Download the Driver
If Windows couldn’t find the driver for you, you’ll need to download it. You can head over to the Tiny AVR Programmer GitHub repository and grab what you need there, or you can click the link below to download the zip file directly.
After downloading your driver, extract it from the zip folder. Don’t forget where you put it!
Step 4: Open the Device Manager
To install the driver, you’ll need to first open up the Device Manager. From the Control Panel, go to the System and Security section, click System, and click on Device Manager. (Alternatively you can Run devmgmt.msc).
In the Device Manager, open up the LibUSB-Win32 Devices tree and you should find a USBTinyProgrammer with a yellow warning triangle hovering over the icon.
Right-click on the USBTinyProgrammer device, and select Update Driver Software…
Step 5: Driver Pointing
On the Update Driver Software window that appears, select Browse my computer for driver software.
On the next window, Browse for driver software on your computer, set the driver search location to the folder you downloaded and unzipped in step 3.
Then click Next, and the driver will begin updating. Shortly after that, though, a Windows Security window should pop up to let you know the driver isn’t “signed”. Click Install this driver software anyway. We promise it won’t damage your computer!
Then play the waiting game for a moment, and wait for a happy Windows has successfully updated your driver software window.
After closing that success window, your Device Manager should have an entry for USBtiny under LibUSB-Win32 Devices.
